I try to think with logic so given that we have both, micro and macro, it doesn't seem foolish to begin there. We have tools, microscopes and telescopes to help us understand both. As we continue on a course of exploration we may find that there is more of a link than the fact of our existence to both, but that there are means within our Universe that would allow us to move from one dimension to another. Of course I am talking of black holes where so far we find little of even light that can escape it's pull. If all that passes into a black hole is furthered out somewhere else, if being the operative possibility, where might that somewhere else be? Certainly within our Universe but on what dimension? Anyway, just postulating again so this is why it is so important for us to continue to explore our two frontiers.
If we survive the trumps and do not destroy what modern advancement we have made I can foresee a near future that is not too distant where we are able to make these questions of dimension come to reveal themselves. As soon as we can perfect space propulsion with efficiency and conquer zero gravity in space, we would then be able to get a better idea of what forces in the outer macro world apply directly to the forces that exist within the micro world. My hunch is that the the micro world and the macro world will align much more closely once we are able to understand both better.
